1. A linear lighting device comprising:
an elongated housing defining a cavity extending along a longitudinal axis of the housing; and
a plurality of lighting modules, the plurality of lighting modules comprising one or more master modules and one or more drone modules, each of the one or more master modules and one or more drone modules comprising:
a printed circuit board configured to be received within the cavity of the housing;
a plurality of emitter modules mounted to the printed circuit board in a linear manner, the plurality of emitter modules comprising one or more emitters configured to emit light;
a drive circuit mounted to the printed circuit board and configured to conduct drive currents through the one or more emitters of the plurality of emitter modules; and
an emitter control circuit mounted to the printed circuit board, the emitter control circuit configured to control the drive circuit to control an intensity of the light emitted by each of the emitter modules;
wherein each of the one or more master modules further comprises a serial communication circuit mounted to the respective printed circuit board and configured to receive messages via a serial communication bus; and
wherein, in response to the messages received via the serial communication bus, the control circuit of each of the one or more master modules is configured to control the plurality of emitter modules mounted to the printed circuit board of the respective master module and to transmit, to at least one of the one or more drone modules via a respective drone communication bus, messages for control of the plurality of emitter modules of the one or more drone modules.
